There are also different kinds of workers... Gearman and TheSchwartz. They are used in different scenarios.
Gearman is typically used when we have things we need done quickly, the user is waiting. I.e., the search system uses a Gearman worker to send out the search job to Sphinx. The directory search also uses Gearman. The image resizer uses it. "Do this right now" kind of tasks.
TheSchwartz is for things that must be done, but they could take a while and we don't care if they're done right now. "Do this sometime, just make sure it runs" things.
